Because of the recent USA Today news report regarding Seresto Flea Collars causing pet deaths, we are putting out a statement detailing our feelings on the matter. Seresto Flea Collars first became available in 2012. As we do with all products and medications, we do our due diligence in researching the product and waiting to see if adverse reactions are noted by other clinicians or outlets. Killian Hill Animal Hospital did not start recommending Seresto Flea Collars until late 2014. After careful evaluation, we deemed the product safe, trustworthy and effective in killing fleas and ticks. As of today, we have sold well over 3000 collars and we have NOT had one fatal adverse reaction. As reported by many, we have seen occasional adverse reactions related to dermatitis and skin inflammation at the site of the collar. These resolved by removing the collar and sometimes applying a topical cream. We have had a couple of clients report that the collar made their pet either hyper or sedate or jumpy. None of these were truly proven to be collar related, meaning when the owner re-applied the collar the behavior did not recur.
Elanco, the manufacturer of Seresto Collars, issued the following statement: There is no established link between death and exposure to the active ingredients contained in Seresto. As a globally marketed product, more that 80 regulatory authorities around the world, including the US EPA, rigorously reviewed the safety data collected over the course of Seresto's development prior to registration and/or approval, as appropriate. The safety and efficacy of Seresto are continuously monitored and scrutinized by global regulatory bodies as well as via internal processes. All adverse events, product related or not, are collected, evaluated and reported. IT IS CRITICALLY IMPORTANT TO UNDERSTAND THAT A REPORT IS NOT AN INDICATION OF CAUSE. Since its approval, the reporting rate for all incidents related to Seresto is less than 0.3% in the US. The majority of these incidents relate to non-serious effects such as temporary hair loss and mild skin irritation around the application site. It is important that consumers purchase collars from a authorized clinic or retailer to ensure the authenticity and integrity of the products they are buying.
The USA Today viral news story indicates "reports" of adverse events without data or explaining what these were. The original individual who is claiming that the collar caused her Papillon to seize and die, declined a necropsy (like an autopsy). Thus, although she is now blaming Seresto for her pet's death over a year later, there is absolutely no evidence to back this up. Assuming the dog even experienced a seizure, there are many more likely causes for a small dog to suffer a fatal seizure. Since the pesticides in the collar are not absorbed into the pet's blood stream, like many other flea and tick products, it is extremely unlikely that the collar had anything to do with the death, except being an easy scapegoat. IT is also important to differentiate the EPA from the FDA. Anyone can make a complaint to the EPA, true or not, and the EPA is required to report it. The USA Today article is referencing complaints made to the EPA, not the FDA. As of right now, we suspect people have misrepresented or misinterpreted information. Furthermore, some individuals are reporting adverse reactions from other flea and tick preventative products which are getting included in the viral Seresto reaction hysteria.
If evidence were to be released of a true health concern, we will be sure to immediately send alerts to all of our pet parents. KILLIAN HILL ANIMAL HOSPITAL CONTINUES TO RECOMMEND SERESTO COLLARS AND WE WILL CONTINUE TO USE THEM ON OUR OWN PETS.
If you are not comfortable with continued use of Seresto, we will be happy to discuss other safe options for your pets. Please do not discontinue the use of Flea and Tick Products, as we know that may tick and flea borne diseases can cause severe illness and death to pets.
